Improvement in scrapers



t. NITE alli STATES STEPHEN ROSSMAN, OF GREENVILLE, MICHIGAN.

IMPROVEMENT IN SCRAPERS.

Specification forming part of Letters Patent No. 145,98*?, dated March24, 1874; application tiled February 1S, 1874.

To all whom it may] concern:

Be it known that I, STEPHEN ROSSMAN, of Greenville, in the county ofMontcalm and State of Michigan, have invented certain new and usefulImprovements in Road-Scrapers; and I do hereby declare the following tobe a full, clear, and exact description' of the invention, suoli as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part ofthis specification. y

My invention relates to an improvement in road-Scrapers, and consists ina peculiar combination and arrangement of levers, chains,

and stops, whereby the scraper may easily be drawn back after dumpingwithout stopping the team, and whereby, also, the scraper may be so heldas to serve the purpose of a roadleveler.

The accompanying drawing represents my invention.

A represents the tongue of `a road-scraper, and B the scraper. Bars care rigidly attached to the tongue7 and bystaples movably attached tothe scraper, thus allowing the scraper a swinging motion backward andforward, so that it may be set at any required pitch. Crossing the endof the tongue at right angles is a bar, b, which gives support to barsa. Passing through the ends of bar b, and also through the bars restingupon them, are the shanks of hooks c, which are bolted or otherwisesecurely fastened beneath. Extending from hooks c to staples d in thehandles of the scraper are chains c, which prevent the scraper fromfalling back too far. The scraper is held in place and kept from dumpingby a notch, g, in bar h, which engages with a suitable stop, la, on theupper part of the scraper. By lifting bar h the notch is easilydisengaged from the stop, and the load is immediately dumped. Bar h isattached to the tongue, so that it will slide backward or forward, thusaltering the relative position of the notch to the scraper, and givingthe desired. pitch to the scraper. This is accomplished by means of aseries of holes, n, in the tongue, by a removable pin, o, and by lugsfm, projecting from the end of bar h, and arranged to clasp the tongueand slide upon it. In each lug is a hole corresponding in size to theholes a. Iivoted midway between the tongue and the scraper, on the barh, is the short bar or lever, r, which is connected by a chain, u, tothe round or cross-bar s of the handles of the scraper. On lever h, justin front of the point where the short lever r is pivoted, is a stop, t,which prevents the short lever from falling too far forward. By drawingback the short lever, after the dumping has taken place, the handles ofthe scraper are brought within reach of the operator, and the scraper isagain brought into position without impeding the progress ofthe team.

After the scraper is half-dumped,77 by depressing the short bar r as faras the chain will admit, and by holding it down, the roadscraper may bechanged into a road-leveler.

The blade of the scraper is always kept sharp, as each side` isalternately rubbed or whetted on the ground during loading andunloading, the team being in constant motion.

What I claim, and desire to secure by Letters Patent, is-

l. The scraper B, in combination with bar h g, lugs m, and tongue A,having a series of holes, a, in its rear end for adjustment,substantially as set forth.

2. The combination of the bar h g, lever r, and chain u, for drawing thescraper back, substantially as specified.

3. The combination of the tongue A, lugs m, bar h, lever r, chains c u,notch g, scraper B, and bars a, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my Ahandthis 13th day of February, 1874.

STEPHEN ROSSMAN.
